Car warm-up only takes 1 minute. The harm of not warming up the car includes: causing engine wear as the engine oil settles at the bottom when the car is cold, leaving the engine internals in a state of dry friction. The method for warming up is: after starting the vehicle, let it idle for 1 to 2 minutes to allow the engine coolant to reach normal temperature before driving. The benefits of warming up are: 1. After prolonged parking, the engine oil flows back into the oil pan, leaving the upper part of the engine without proper lubrication; warming up helps lubricate it. 2. When the engine hasn't reached operating temperature, the fuel system cannot effectively vaporize gasoline completely due to low temperature; warming up improves efficiency. 3. It helps the transmission gear oil to lubricate the upper part of the transmission.

Will there be any impact after resetting the transmission?

Resetting the transmission may have some impact, such as increased fuel consumption and gear shifting jerks, but these issues will resolve after some time because the transmission's computer has a learning function. There are three common types of automatic transmissions in vehicles: dual-clutch transmission (DCT), automatic transmission (AT), and continuously variable transmission (CVT). The dual-clutch transmission simply adds an extra set of clutch and shift control mechanism compared to a manual transmission. One set of clutches controls the odd-numbered gears, while the other controls the even-numbered gears. The CVT transmission offers relatively smoother gear shifting. The AT transmission is an automatic transmission with a complex structure and mature technology.

Why does the Passat's air conditioner blow hot air on one side and cold air on the other?

Reasons for the air vents blowing hot air on one side and cold air on the other: 1. Temperature settings differ on each side: Dual-zone air conditioning requires adjusting the temperature for both the driver's and passenger's sides. If one side is set higher than the other, it may result in one side blowing hot air and the other cold. 2. Incorrect adjustment of the hot/cold knob: For example, wanting hot air but the knob is not turned to red, or wanting cold air but the knob is not turned to blue. 3. Insufficient or excessive refrigerant. 4. Clogged heater valve: Automatic dual-zone air conditioning uses two pipes to the heater core. If one is clogged and the other is not, the temperature will differ on each side, resulting in different air temperatures. 5. Damaged stepper motor. 6. Malfunction in the air conditioning computer: This can cause the control of the hot/cold pipe valves to fail. Try resetting the computer. 7. Low compressor power or abnormal high/low pressure.

Do Car Stickers Affect Annual Inspection?

Car stickers do not affect the annual inspection, but the area covered by the stickers must not exceed 30% of the vehicle's body. If it exceeds 30%, it will affect the vehicle's annual inspection. Annual inspection, also known as annual review in more colloquial terms, refers to the safety inspection conducted every year or every two years on a vehicle. This includes a comprehensive check of components such as the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, and license plate installation. Annual review implies a routine examination conducted on a yearly basis, while annual inspection is often used more formally, such as for checking certain official IC cards, but annual review is more commonly used in everyday life.
